One uses the information on this website at your own risk. Most applications listed have been installed and tested on my Nokia N900. There have been times when software has locked up or hung my N900 or times when I have had to reflash the device. (Lots of times). I have installed software even when websites have said it will causes crashes. It is best to only install tested software, but its entirely up to you what you install on your device, just realize the risk and be responsible. Always backup your N900 before installing anything that might contain some risk.
